The circulating fluid set temperature can be set by specifying the circulating fluid target
temperature during Serial Remote mode.
If the temperature exceeds the upper limit of the circulating fluid set temperature range, the
circulating fluid target temperature is changed to the upper limit value. If it is lower than the lower
limit, the circulating fluid set temperature is changed to the lower limit value.

The operation can be controlled by sending the operation start command during Serial Remote
mode.
0=Stop 1=Start
5.10.6 Setting of the Upper Limit of the Output
